Fix for syncing errors in xbox (HELPED ME MOJANG FIX THIS)

my worlds were deleted kinda the game synced and my data was lost but i had an fix sync from the cloud until 50% then cancel this may like me restore your worlds this is becase the sync says do you know this world adress before actully doing anything and if its there minecraft finds it but if 100% the sync gives stuff to minecraft that minecraft dosnt understand anymore or is an new thing for it so it thinks its saying delete the data there is no storge so it deletes them the first sync that is really fast happans just deletes those addresses but the one with those %s actully deletes your data and people dont know this. MOJANG FIX THIS yes this is an real thing and xbox minecraft players have to get realms for an safe backup if you like me can pay also 3.99$ for an backup tab the improtant worlds tab play on realm if you dont have an realm get the realms core for 3.99$  and check its activated before this(i mean in your realms tab you can see it) then select your realm after pressing play on realm then select the first slot and wait come back it will bring you to the realm go to settings saves save current world go an your laptop/PC open minecraft go to the same saves in settings find your manual backup then tab on the there dots then tab download world then go to the world settings export the world it will give you an file and thats your world backup hope this helped i know there is an app named mc world downloader but it didnt work for i it uses sync and those are curropted
